I have been running this 300w Finnex HPS heater on my 90 gallon with 36 gallon sump for two months now and love it. It is easy to dial in at any temp you want with a digital screen to 0.1. Comes in very handy when wanting accuracy and stability for any aquarium. I am actually buy a second one as I am tying in another 50+ gallons to my existing set up. Great product.

Nice features, but doesn't last longBy Johnon 2/18/2012

I bought 2 of the 300 W heaters because the reviews seemed overall positive. I used these heaters (one at a time) on my 75 gallon marine tank. The first one lasted only one week when the temp went from 80 to 70 within one day. I replaced that one with a second heater and that one (set to 80) is also slowing loosing ground (tank is now down to 76) after only 2 weeks of use. Hard to believe that I just happened to get two defective heaters. These are made in China, which might explain the short life-span.

I have this 300w heater in my 200 gallon system. 125 display tank, 75 gallon sump and it keeps my water at a steady 79-80F. My ambient temperature is 71F and this heater does a great job for its size. It's like half the length of other brands with the same wattage. Fits great in those sumps that aren't so wide/tall.

Not happyBy Vincent on 1/29/2012

I purchased one of these 300 watt heaters recently because of the reviews. However, I am not impressed. The first one I had shattered inside of my sump for some unknown reason. BRS was great about it and sent me out a replacement the very next day. Tonight when I came home I noticed that my tank was down to 74.5 degrees when I keep it at 80 degrees. For some reason the heater quit working. I tried troubleshooting without success. I will not by one of these again.

I purchased the 300w heater and it worked great, I was really happy with it. That is until is stopped working yesterday. I contacted Finnex and am waiting to hear back from them on a warranty replacement.

I have owned 4 of these heaters in the last 6 months, only one of which is still working. QT heaters thermostat malfunctioned killing my poor fish. Other two just stopped working after 3-4 months. Thankfully I use two heaters in my DT so the whole tank didnt crash. they look nice and have a nice price tag but aren't reliable.

i really like my 200w finnex heater. the digital display is great and has proven to heat accurately against my two other thermometers in the tank. great value!

Seems like value but doesn't last long and poor warrantyBy Matthewon 12/12/2011

My QT HPS-100 quit working on me after about 3-4 months of total use, of course this was 8 months after I purchased it (only used QT a few times)so Finnex wouldn't replace it.

Unfortunately, I purchased a HPS-300 for my display tank right before the HPS-100 stopped working (big mistake). That HPS-300 lasted about 2-3 weeks of use before it stopped heating, nearly killing off my tank. In the process of getting that one replaced.

Seems like a lot of value for a heater and a very nice package/design. But from my experience over the last 8-9 months I would not recommend this heater series to anyone. One lasted about 3-4 months, while the other one lasted about 2-3 weeks. In addition, with a warranty of 6 months from date of purchase I would never risk purchasing this heater again.

so far so goodBy Johnon 12/11/2011

I just got two of these and they work real well. Time will tell how durable they are. I really like the digital temp display, so it is easy to see when they are on in my sump.

Only one complaintBy Mikeon 12/10/2011

I'm happy with the heater overall. Very easy setup and holds temp in narrow enough range. My only problem so far is that the suction cups slide around on the glass. I'm not sure if it's due to algae film on the glass but my other in tank suction cups haven't had any problems. This one started sliding around after about 4 days. However, the cups are holding the heater in place at this time so it's alright for now.
